Dana Incorporated has launched Spicer HVT1, an advanced power-split transmission that improves and sustainability of agriculture telehandlers.
The new-gen transmission supports power inputs from 110 to 155 horsepower (80 to 115 kW) and offers fuel savings of up to 30% compared with agriculture telehandlers that use conventional transmissions.
Currently undergoing field tests with several global original equipment manufacturers, the transmission leverages more than a decade of the company's expertise in developing hydromechanical variable transmissions for the off-highway market. It already produces market-ready HVTs for construction, agriculture, material handling, and forestry applications.
It supplies significant advantages across the board over existing competitive conventional transmissions, helping next-generation telehandlers achieve new levels of productivity, performance, control, refinement, fuel efficiency, ease of use, and operator comfort.
Performance
The unique design of the Spicer HVT1 provides numerous benefits that address the expanded performance expectations of agriculture telehandlers operating in the farmyard, field, and road.
Its distinctive combination of hydrostatic and mechanical drives in an integrated 90-degree gearbox offers precise low-speed manoeuvring control and smooth, progressive response for loading and handling cycles. It also delivers improved climbing and high-speed towing capabilities up to 31 mph (50 km/h).
In addition, it allows agriculture equipment buyers to increase the utilisation of telehandlers by supplying maximum torque for a wide range of rigorous work demands, such as digging and loading.
To maximise machine productivity in widely varying duty cycles, the transmission uses an advanced electronic control system to continually adjust the mix of hydrostatic and mechanical power, allowing the engine to maintain a consistent speed in its most efficient operating range. Besides, it also improves operator ergonomics through simplified handling, smoother shifting, lower machine vibration, and reduced noise.
Additionally, the HVT1 fits within current telehandler design envelopes, providing OEMs with the option to specify a downsized engine that achieves the same performance as a conventional transmission or uses the same size engine in a powertrain supplies vastly improved performance.
